Hi there,
I thgt i should also add some observations from my end regarding the DRI and
AGP issue. I was atlast able to get my Radeon driver support for my Laptop.
Compaq Presario 1720 US, with RH 7.2, Kernel 2.4.7-10, XFree86 CVS Oct 31st
8 MB Video Ram, ATI Radeon Mobility M6
Observations:
1) When i pass "vga=0x305" to my kernel during bootup (in the lilo.conf). No
matter what I do, my X never runs if i use a Radeon driver. I had to use
Vesa generic driver to get my X running till now. I have also tried with
different options available for the "vga" parameter, but X runs only when i
choose "vga=1" option (i.e. 80x25). If i do choose to run with "vga=0x305"
kernel option and with "radeon" as my driver for the X, then i am only able
to get 640x480 screen and that too in a screwed up manner.
2) So i am able to run the X with a radeon support. Here is where i found
some bizzare things:
* If i set up my X server to a "1024x768x16", i get AGP 4x and also my DRI
is enabled.
This information was gathered from XFree.0.log, but when i try to
run the "glxinfo"
it says that my "Direct Rendering : no". Why is it saying so ???
* When i set my X server to "1024x768x24", i get the display but then
my AGP and DRI options are ignored while the X starts.
In both cases, glxinfo reports that my "DRI" is disabled irrespective of
what is shown in XFree.0.log.
And glxgears gives me 250-270 fps. Can anyone tell me what should be the
ideal number on would expect to see if everything was working, for a Radeon
Mobility M6 chip ?
So here are my questions:
1) Can i still pass vga=0x305 (or any other option) and still get Radeon
support for my card ? If so what resolutions are we talking abt ?
2)Why isn't the DRI and AGP enabled at 1024x768x24 res. ? And why is glxinfo
reporting it incorrectly when i see that DRI is enabled in my XFree.0.log
(while using 1024x768x16 res) ?
3)What is the typical fps reported from "glxgears" for this videocard ?
Lastly, i was never able to get a higher resolution to work for me unlike
what Jean has reported.I will send in log files if someone is curious.
Seasons Greetings :))

OK, I finally got AGP to work, using *only* CONFIG_AGP_INTEL. And I got
DRI working at 1280x1024. Unfortunately, I can't get it to work at
1400x1050 (SXGA+), which is my normal LCD resolution. It complains that
it can't allocate 8663 kB of memory, which is normal since I only have 8
MB video memory. Is there any way to "save some memory" so that I could
get DRI @ 1400x1050?
Thanks,
Jean-Marc
